How do lasers work in dentistry?


All lasers work by delivering energy in the form of light. When used for surgical and dental procedures, the laser acts as a cutting instrument or a vaporizer of tissue that it comes in contact with. When used for "curing" a filling, the laser helps to strengthen the bond between the filling and the tooth. When used in teeth-whitening procedures, the laser acts as a heat source and enhances the effect of tooth-bleaching agents.


What Are the Advantages of Using a Laser in Dentistry?


Compared to the traditional dental drill, lasers:


• May cause less pain in some instances, so reduces the need for anesthesia

• May reduce anxiety in patients uncomfortable with the use of the dental drill

• Minimize bleeding and swelling during soft tissue treatments

• May preserve more healthy tooth during cavity removal
